Factor the following:
15 x y - 45 x - 6 y + 18
Factor 3 out of 15 x y - 45 x - 6 y + 18:
3 (5 x y - 15 x - 2 y + 6)
Factor terms by grouping. 5 x y - 15 x - 2 y + 6 = (5 x y - 2 y) + (6 - 15 x) = y (5 x - 2) - 3 (5 x - 2):
3 y (5 x - 2) - 3 (5 x - 2)
Factor 5 x - 2 from y (5 x - 2) - 3 (5 x - 2):
Answer: 3 (5 x - 2) (y - 3)
C because u have 3/7 which is a fraction
X = 40°
y = 6
hope this helps!
Answer:
(C) reflection on y = -x
Step-by-step explanation:
There are vertices on the x-axis, the y-axis, and the line y=x (point Q(3, 3)), so reflection on any of those lines will result in a point being invariant. The only line of reflection among the choices given that does not contain a vertex of the figure is y = -x.
reflection on y = -x will give no invariant points
